Immature and having fun are two different things.
Immature is plain out stupid.
Having fun is NOT pissing anyone off [[at least you're not doing it on purpose.]]
Immature boys and girls are irritating.
No joke about that! They get the attention
but they are all for the WRONG reasons!

I think that kids that are 11, 12, 13, 14, 15,16 are immature, although in some cases there are kids
that are pretty grown up for their age. But that's what being a young teenager is, being immature!
But once you're 17 you have to grow up, and stop acting like a kid, seriously, its pathetic to see
older teens act like they're in middle school. or in elementary!!!
And it isn't all right to be immature and above 18 years of age!! That is a lie!!!
If anyone older that 18 is acting immature, they better be doing it alone, and away from other people.

Depends on what kind of imature... Some people act immature and its really just annoying, others know when to be immature and whne to stop, which i guess is fine... Living as a mature person is boring anyway

err its not bad to be immature but its nowhere near good. its anoyying to be imature sometimes too. Like yesterday i went to see the movie You Dont Mess With the Zohan and after it i was with my brother who has autism so when it comes to socializing he sucks at it and hes 21 and these 3 hmm 6th graders ame up and started tlakin to him just being anoyying and immature so then i come up an dim lol over 6 feet tall and havent shaved in a week so i had a little bit of facial hair and im pretty buff so the kids start backin off and this one kid lol wanted to fight me and thne his bro came who was my size and lol guess wat immaturity must run in their family bc the guy started makin fart jokes, anyways to make along story short i threatened to kick his ass and then he backed off. im nto sayin im some badass but lol immature kids tend to stfu at the right time
